UNITED STATES ENVELOP-SEALING m-non'mn.

To all whom it may concern:

Be it known that I, HENRY JAMES REY- NOLDS, of the city of Chicago, in the county of Cook, in the State'of Illinois, one of the United States of America, have invented cer-- tain new and useful Improvements in En velop-bealing Machines, of which the following is the specification.

My invention relates to improvements in envelop sealing machines, and the object of the invention is to devise a simple, cheap and effectual machine of this class, which will moisten, close and seal any sized envelop from a small pay envelop to a large official sized envelop without the necessity of any adjustment. i

A further object is to make such a machine as may be manipulated by hand and yet feed, close, seal and deliver the envelope with great rapidity. n

' My invention consists of a suitablebase, a water well superimposed thereupon'at one end, a'conical moistening Wheel secured on a spindle journaled in bearings at the top of the well, a guiding plate located in advance of the disk, a suitable standard provided with feeding and delivery rollers, one of which co-acts with'the conical measuring wheel, a folding plate extending between the spindles of two of'the feeding rollers, and a suitable driving gear and handle operating the rollers all constructed and arranged as hereinafter more particularly explained.

Figure 1, is a perspective view of 11'ly"'lIl1- proved envelop sealing machine, portion being broken away to more clearly exhibit the construction thereof. Fig. 2, isa plan view. Fig. 3, is a cross section looking toward the forward end ofthe machine and on a plane substantially'on a line w-y Fig. 2. Fig. 4, is a detail of the advance guiding plate. Fig. 5,is a detail of the folding plate for the envelop flap at the opposite end of the machine.

the base of the coneinnerrnost. The .wheel B is secured on a spindle C,fwh'1ch is jour-' naled 1n bearings C extending upwardly from the well B.

D is a plate secured to the back of the: well close to the back of the hollow conical wheel B. p

E is.-the advance guiding plate, which is Substantially reverse V-shape in cross section being provided with an end E and rojecting wing E lying flush with the inclined face or side E of the plate E. The other face or side E is preferably vertical. A'

slot E is made in the end E and through this slot extends a fastening bolt 2 (see'Fig. 1) whereby the plate E is fastened, so that PATEN oFFIon f 7 Patented J an. 4, 19.10. I Application filed February 26, 1909. Serial No.480,166.

the top'edge is on a line with the top edge of v the plate D.

F is a standard attached to or forming part of the .base A and carrying at the top the bearing plate F.

F is an arm depending from the front end of the plate F.

G is a spring fork, whichis fastened to the arm F by screws G.' between its jaws the roller H, which is preferably formed of rubber or other suitable The fork G carries I yielding material and normally presses against the upper portion of the i cone-" shaped wheel In order to adjust the tension of the roller ll upon the cone-shaped wheel I pro \ldt a set screw I, which is shouldered and extends through the spring plate G into the H arm F 1 The shoulder abutting against the plate will serve to press the plate inwardly or allow it to give outwardly in orderto obtain the desired pressure of'th'e roller "H upon the cone wheel B. v

J J are spindles journaled in bearings'in the base A and in the plate F.

J 2 and J are yielding rollers preferably of rubber, which are located toward the lower portithi of the spindles for a will lidreinafter appear."

K the folding plate, which is fastened tolthe standard F by means of screws K expurpose, which tending through slots K in the plate. The

plate K isreverse 'V-shape' in cross. section and has a flaring -lip;K* at the front end, which serves to guide the open flap of the envelop and aid in its depression into the vertical or foldin position by the time it reaches the substantia ly 'vertical portion K as will passes; 1

hereinafter appear. Theslots K? are designed to set thefplate K in its proper position, so that it extends slightly above the "level-of ".the' extension. D of the plate D,

*which forms a track along which the angular corner of the envelop to the inner side of the L- arespindles journaled in the base and plate F.

' "L and L are yieldingrollers also preferably made of rubber and designed to seal and deliver theen'velop. The rollersH J 2 J 3 and L and'L are alsoipreferably' made of in '1 and carryin a sprocket wheel M T is the crank han le by which the spindle M is turned. I V N-- is a sprocket chain extending from the g procket wheel M to a sprocket wheel 0 on the spindle C.

also the The inner endofthe spindle M carries the bevel gear pinion M which meshes \vitha bevel ge'arJ on thespindle J r J is a gear wheel securedat the upper end of thespindle J The gear wheel J meshes witha gear wheel 3 journaled on a stud 4 in the plate F and the gear wheel 3 meshes with a gear wheel L at the upper end of the spindle L. r I

It will now be seen by turning the crank wheel N the main wheel B will be' turned as yielding rollers J -and J a and L and L v The envelop is placed in, the position shown in dotted lines astride the substantially V-shaped plate E, so that it may be takenhold of by the roller H. The ,fiap 0tv the envelop extends over the cone-shaped wheel and the ;'roller H as the cone-shaped 'Y wheel is rotated as hereinbefore described carriesthe envelop forwardly by its flap ove'r the plate D and extensionD" and under a the plate K. The gummed under portion of i the flap is moistened by means of the film of water, which is maintained constantly on the cone wheel B in its rotation in the waterin the well. The moistened envelop is car'- ried bythe roller H until the lower portion of the envelop passes between the rollers J 2 and J which press upon the lower portion oftheenvelop and serve to carry it still forwa-rdly through the machine.

' The flap of the envelop as it passes underneath the lip K is turned outwardly until by the time it passes to theend of the plate K the vertical side Kthas turned the flap of the envelop intmthe substantially verticalposition. The rollers L and L now grip the envelopj' and efl'ectually seal the sameas 1t;

*passesbetween them, such rollersL", and L serving to deliver the envelop.

'actin spin e and hav ng the base located in prox- Theenvelops' may be fed in over the plate E and delivered very quickly through the machine, and it will be seen that. on account of theconstruction of my machine, that the smallest class of envelop can be fed and delivered with equal facility to the larger sized envelop.

' It will be noticed from what has-been bevfore described that the rollers J andJ catch the lower part of the envelop and this is for the purpose of allowing the flap to pass downwardly 'into substantially the vertical. position as otherwise if the rollers extended upwardly there would be a tendency to prevent the flap lying smoothly as it is passing from the inclined to the vertical position, the distance being short. 4

' Alt-hongh I have shown and described my machine wit great particularity it will, of course, be understood thatvarions changes may be made, which will embody my'invention without departing :t'romthe spirit thereof.
